We had an asset using depreciation key(SLM), useful life 8 years. It was acquired on may 2012 with incorrect value of say 100000 including vat. In 2013 december the accounting people say that the asset capitalization should be excluding vat amount of 10000 i.e. 90000. SAP posted depreciation for both 2012 and 2013 on 100000. In 2013 december an adjustment was made bringing down the asset value to 90000 and the excess depreciation difference for 2012 and 2013 was adjusted using ABZU-write up. Now when in 2015 i am trying to close 2013 asset accounting system is giving an error saying planned depreciation not posted completely. Business does not want this depreciation to be posted as everything is already adjusted. Without posting planned dep SAP is not allowing to close 2013. Can anybody give a suitable solution for this. I tried posting the planned depreciation but sap is not allowing me to reverse it saying depreciation key does not permit.
